The defense played a police video of the mother's interrogation hours after the shooting.

At one point in the video, a police detective tried to double-check West's story about the attack by suggesting there might be surveillance video that didn't show any young black males anywhere near the crime.

Even though the surveillance video didn't really exist, the detective was trying to find out if West was in any way involved herself.

"Look, I'm not afraid so, you know, nobody's gonna tell me I did something I didn't do," she replied to the detective.

The defense then called Georgia State University Psychology Professor Dr. Heather Kleider to suggest West may have identified the wrong gunman.

Kleider said victims of such trauma usually focus on the weapon pointed at them more than on the face of their attacker.

She said in her opinion, the video of the police interrogation showed detectives trying to influence West's identification of Elkins.

"She never at any point in time, during what I saw, said, 'this is the person; I'm absolutely sure'," Kleider testified.

The defense also called Argie Brooks to the stand to try and attack his credibility as the person who first led police to suspect Elkins.
